i Application filed September 6, 1898.` Serial No. 690,316. (No model.) A

in the county of Jones and State of Iowa, have invented a new and useful Combined Punching, Shearing, and P1ow-lVelding` Machine, of which the following is a specification.

The invention relates to a combined punching, shearing, and. plow-welding machine.

`The object of the present invention is to im` prove the construction of the machine shown and described in Patent No. 540,275, granted to :me June 4, 1895, and to increase the strength, durability, and `efeiency of the same, and to enable the machine t0 be employed for welding plowshares to the landside of plows.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated' in the accompanying drawings, and pointed out in the claims hereto appended. y

In the drawings, Figure'l is a perspective view of a machine constructed in accordance with this invention, showing the front side thereof. Fig. 2 isa similar view showing the rear side of the machine. Fig.A 3isaperspective view showing 'the parts arranged for sharpening horseshoe-calks. Figs. 4 and A5 are transverse sectional views. Fig. 6 is a detail perspective view of the punch, showing the parts separated. Figs. 7 8, and 9 are detail views showing the parts of the device for operating on plows.'

Like numerals of reference designate correspending-parts in all the figures of the drawings.

integral with a iat base-plate 2 andcoperating with a movable jaw 3, which is pivoted at its rear end to the stationary jaw by a transverse bolt 4 or other suitable fastening device supported at one side of the machine for the reception of bolts or other suitable fastening 'devices and is mounted on abench 6, but any other suitable support may be employed.

The stationary jaw and the base form the body portion of the machine, which is provided at its front with an integral curved rack- 1 designates a lower stationary jaw formed The flat base-plate is perforated bar 7 connected with the stationary jaw by upper and lower rack-bars 8 and 9. The curved rack-bar, which has a smooth inner or rear edge, is provided at its front edge with teeth that mesh withcorresponding teeth 10, formed on the head of `an operating-lever 1l,

andthe latteris connected with the movable jaw 3 by a substantially triangular link-frame 12, composed of two similar sides and having its base extending across the rack-bar 7 The sides and bottom of each member of `the link-A frame are formed integral with one another. `The upper end of thesaid frame 12 is pivoted to the front end of the movable jaw at 13, the sides or members being located at opposite sides of the same, and a roller 14 is located at the lower inner angle of the frame and slides on thesmooth inner edge of the rackbar to reduce the friction to a minimum. By oscillating the operating-lever 11 itsteeth are caused to mesh with those of the rack-bar, and the pivoted jaw 3 is moved to and from the stationary, jaw and this movement is utilized for operating the punching, shearing, and plow-welding devices hereinafter described.

The stationary and movable jaws are provided at their adjacent edgesrwith suitable knives or blades 15 and 16, and in order to hold the material down to the work a hook 17 is employed. i The hook 17, which is clearly illustrated in Figs. 3 and 5 of the accompanying drawings, consists of a shank and a head and has its bill 18 elongated and disposed at right angles to it. The inner side or edge of the opening of the head of the hook is flush with the upper edge of the stationary jaw, and the bill 18, which is located above the stationary jaw, is adapted to engage the material operated on. The shank of the hook is perforated for the passage of a horizontal rod or pin 19, extending transversely through the stationary jaw, as clearly shown in Fig. 4 of the accompanying drawings, and having one end threaded to receive a nut 20, which is preferably provided with a handle to enable it to be screwed tightly against the hook. The other end of the rod or pin 19 is provided with an eye or head 21,which receives a punch 22, consisting of ashank or body portion provided at the top with a head 23 and having a socket 24 at its lower end to receive a tool IOO 25, secured in place by a clampingscrew 26. By this construction the tool and the body portion 22 are separate, and by connecting them in the manner shown a minimum amount of metal is required for the tool, which may be readily removed and replaced. The head 23 is rounded and iits in a horizontal socket or eye 27 of a dovetailed block 28, which is litted in a corresponding recess 29 of the movable jaw, as clearly illustrated in Fig. 1 of the accompanying drawings. The transverse or horizontal eye 27 is provided at the bottom with an opening to receive the neck of the punch, and the opening is of sufficient size to permit the necessary play of the parts incident to the pivotal movement of the jaw 3. The punch is guided in suitable ways 30,

formed by parallel bosses or iianges, preferably integral with the stationary jaw and located at the top of an opening 31,'between the central portion of the stationary jaw and the base 2 of the machine. The bosses or iianges ot' the ways 30 are also provided at their inner faces with corresponding grooves 32, which form a seat for the .eye or'head 21 of the rod or pin 19, and the latter retains the punch in the eye of the block 28, and as the inner end of the eye is closed, as illustrated in` Fig. 4 of the drawings, the said rod 19 will also retain the dovetailed block in the recess of the movable jaw.

The flat base-plate is provided at a point opposite the punch with an annular boss or enlargement 33, on which is seated a rotary die or head adapted to coperate with the punch and provided with an annular series of apertures of dilerent sizes. The die or head 34, which is adapted to be adjusted to bring any one of its apertures beneath the punch, is provided with a central threaded opening to receive and engage a threaded upper end 35 of a pivot or pin 36, which passes through registering perforations of the base or bed of the machine and the bench. The lower end of the pin or pivot 36 is provided with a head and is threaded adjacent to the same to receive a nut 37, which engages the lower face of the bench, whereby the die or head is retained at any desired adjustment.

The stationary jaw is provided with an integral iiange or ledge 38, which supports a plate 55. The lower or outer end of the supporting-plate 55, which is stationary, is pro vided with an eye 56 to receive a pivot or stud 41, and its rear end has an outwardly-k extending arm 57, provided with a perforation 58 and having opposite lugs 59, arranged to support a stationary welding-jaw 60. The

v welding-jaw 60 has an upwardly-extending blade portion and is provided with a bottom portion or arm 6l, conforming to the contiguration of the arm 57 of the supporting-plate and provided with a perforation 62, registering with the perforation 58 and receiving a pin or bolt 63. The welding-jaw 60 has a beveled welding edge and is provided with a centrally-arranged rearwardly-extending lug 64, which iits in a corresponding recess 65, formed in a flange 66, extending upward from the back of the supporting-plate 65.

The stationary weldin g-j aw cooperates with the movable welding-jaw 67, consisting of a plate or body provided at the top with a head or enlargement 68, having an eye to receive a pivot or stud 49, and the jaw 67 and the supporting-plate 55 are retained in position by suitable clamping-screws mounted on the eyes of those parts and engaging the pivots or studs 41 and 49, as clearly shown in Fig. 1 of the accompanying drawings. The enlargement 68 forms a lower shoulder, which is beveled to form a welding edge 69, and the lower portion of the bodyV or plate of the weldingjaw 67 depends below the welding edge and supports the point of the plowshare in weld-V ing the same.

The bolt or pin 63, which \passes through the registering perforations 58 and 62, is provided with an eccentrically-arranged head 63a, which works in the perforation 62, and when the 'pin oribolt is rotated it is adapted to slide the lower welding-jaw laterally of the machine and move it to and from the upper welding-jaw, whereby it is capable 'of clamping and rmly holding the landside of a plow between the weldin gjaws during the weldin g operation.

As illustrated in Fig. 3 of the accompanying drawings, the machine may be arranged for sharpening horseshoecalks,and the horseshoe-calk-sharpening device consists of a lower removable die 70 and an upper integral member 71. The die 70, which is substan tially triangular in side elevation, is provided with a depending shank, which iits in a corresponding perforation or socket of the stationary jaw, and the upper member, which presents a lower iat edge to the calk, is carried by the movabie jaw.

Changes in the form, proportion, size, and the minor details 'of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
